Intended Use - Bender ISOMETER iso1685DP-425 Manual

Safety instructions
Unspecified frequency range
When connecting to an IT system with frequency components below the
specified frequency range, the response times and response values may
differ from the indicated technical data. However, depending on the ap-
plication and the selected measurement method, continuous insulation
monitoring is also possible in this frequency range.
There is no influence on the insulation monitoring for IT systems with fre-
quency components above the specified frequency range, e.g. within the
range of typical switching frequencies of frequency inverters (2...20 kHz).
2.4 Address setting and termination
Correct address setting and termination is essential for proper functioning of the
iso1685... series insulation monitoring device.
Risk of bus errors!
Double assignment of addresses on the respective BMS busses can cause
serious malfunctions.
CAUTION
Ensure correct address setting and termination of the device!

2.5 Intended use

This manual is intended for qualified personnel working in electrical
engineering and electronics!
Read the manual before you begin to mount, connect, and commission
the unit. Always keep the manual within easy reach for future reference
following commissioning.
The device is used for monitoring the insulation resistance in large power supply systems
designed as IT systems. The specific measurement technique (AMP
lation resistance also in installations where extremely high system leakage capacitances
to earth exist due to interference suppression methods. The adjustment also to high sys-
tem leakage capacitances occurs automatically.
The device generates locating current pulses required for insulation fault location. That
allows the localisation of the insulation fault using permanently installed or mobile insu-
lation fault locators.
Intended use also implies:
• The observation of all information in the operating manual
• Compliance with test intervals
In order to meet the requirements of applicable standards, the equipment must be ad-
justed to local equipment and operating conditions by means of customised parameter
settings. Please heed the limits of the range of application indicated in the technical data.
Any other use than that described in this manual is regarded as improper.
